Abstract

In a USB device, virtual endpoint capability allows a number of physical endpoints in the device to support a larger number of data pipes at logical endpoints requested by the host. This is done by re-assigning physical endpoints to support the logical endpoint requested by the host. The logical endpoints and their corresponding data pipes may be served in a round robin scheme.
